In LF 2019L, fuel products were created with LF 2016 Remap (LF Remap) vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas using fuel rule sets. More information about 2019L can be found at https://landfire.gov/lf_limited.php. CC is used in the calculation of Canopy Bulk Density (CBD) and Canopy Base Height (CBH). CC supplies information to fire behavior models to; determine the probability of crown fire initiation, provide input in the spotting model, calculate wind reductions, and to calculate fuel moisture conditioning. CC also has capable fuels functionality. The capable fuels process calculates time since disturbance (TSD) assignments for disturbed areas using an "effective year". Year 2021 fuels, for example, may be calculated for the year 2021. This process considers all the existing disturbances included in 2019L and assigns fuels to the pre-disturbance vegetation based on the adjusted TSD, making the products "2021 capable fuels." By synchronizing TSDs for surface and canopy fuels, these refinements improve performance of fire behavior modeling. More information about capable fuels can be found at https://www.landfire.gov/lf_remap.php. LF 2019L is the first update to the LF 2016 Remap conterminous United States (CONUS) extent. This update includes a limited set of products that represent circa 2019 ground conditions. Read more about LF 2019L here (https://landfire.gov/lf_limited.php). LF 2019L products are designed to facilitate national and regional level strategic fire and resource management planning and reporting of management activities. The principal purposes of the products include providing, 1) national level, landscape scale geospatial products to support fire and fuels management planning, and 2) consistent fuels products to support fire planning, analysis, and budgeting to evaluate fire management alternatives. Products are created at a 30 meter raster; however, the applicability of products varies by location and specific use. LF products were designed to support 1) national (all states) strategic planning, 2) regional (single large states or groups of smaller states), and 3) strategic/tactical planning for large sub regional landscapes and Fire Management Units (FMUs) (such as significant portions of states or multiple federal administrative entities). The applicability of LF products to support fire and land management planning on smaller areas will vary by product, location, and specific use. Managers and planners must evaluate LF products according to the scale and requirements specific to their needs. In LF 2019L, fuel products were created with LF 2016 Remap vegetation in non-disturbed areas, but pre-disturbance vegetation was used in disturbed areas. This product has 2021 capable fuels functionality. Units are percent canopy cover. The values of canopy cover are class midpoints. 2019 ground condition Complete Biennially -127.9878 -65.2544 51.6497 22.7654 ISO 19115 Topic Category imageryBaseMapsEarthCover biota USGS Thesaurus fires hazard preparedness remote sensing image collections geospatial datasets geographic information systems None raster digital data Canopy Cover CC U.S. Geological Survey (USGS) U.S. Forest Service (USFS) 2019 Limited Update 2019L Common geographic areas US CONUS United States Continental U.S. Conterminous United States None None LANDFIRE, Earth Resources Observation and Science Center (EROS), U.S. Geological Survey Customer Service Representative physical

Attributes were not validated against in person observations. The products were pixel "truth" tested for consistency of land or water characteristics across all products. Products were formally tested to ensure that valid data was produced for all pixels. Each product was then validated and tested for duplicates, omissions, and errors. Beginning in 2019 LF 2019L products were created using recent advances in image compositing, tiling algorithms, and faster computing hardware to ensure that LF products remained relevant. LF 2019L leveraged the Landsat archive, lidar data, and user contributed field plot data compiled into the LF Reference Database (LFRDB), to create new base map vegetation products. Reference resources included, but were not limited to, Forest Inventory and Analysis (FIA) program plot data (USFS https://fia.fs.fed.us/), Landsat Dynamic Surface Water Extent [(DSWE) USGS https://www.usgs.gov/core-science-systems/nli/landsat], the National Land Cover Dataset [(NLCD) USGS https://www.mrlc.gov/data], and National Agricultural Statistics Service [(NASS) USDA - https://www.nass.usda.gov/].
